Time acceleration - freeze + distance jumps

Hi

I was doing some stretched free flight to understand intercept mechanics within DCS AI world and tried using time acceleration option (CTRL+Z).

It seems to me that in Caucasus terrain this works like expected, it is smooth and fully controllable. In the Persian Gulf, however, the behaviour is different.

When doing CTRL+Z in PG terrain, time acceleration jumps - most of the time everything stops for few seconds, jumps few miles, fly accelerated for 2 seconds and then jumps again...

2x is manageable, but anything above 2x time acceleration causes the above effects. As said, the exact same mission set in the Caucasus works fine with regards to this feature.
